To facilitate research on topic shift dialog modeling, [1]} have developed a Topic-shIft Aware dialoG datasEt (TIAGE) by augmenting the PersonaChat dataset [2]} with topic-shift annotations, which indicate at each turn in a dialog session whether there is a topic shift. It turns out that, on average, topic shifting happens every 4-5 turns in the dataset. The statistics of TIAGE are presented in Table REF .
